5.2.2.2 Global Spanning Tree
To enable the Spanning Tree function, select "1" on the "Spanning Tree" option from the "Switch
Configuration Menu." The Spanning Tree menu will appear as shown in Figure 5-20. Once this screen
appears you will select option number 1, "Global Spanning Tree Parameters," where you will again get a
new screen as shown in Figure 5-21. Here you will need to select "Enable Spanning Tree."
This screen also allows other parameters to be adjusted:
• Priority is a configurable priority for the Bridge: it is a number between 1 and 65534 with "1" being
the highest priority and "65534" being the lowest. The Bridge with the highest priority will become
the root. If the priorities of any Bridges are the same, the MAC address will be used to define priority.
• Hello Time (sec) is the time interval between the generation of BPDUs by the Root. The parameters
can be set so that it will be used if the Bridge becomes the Root of the Spanning Tree.
• Forward Delay (sec) is the time interval between Port state transitions (Learning to Forwarding). The
parameters can be set and will be used if the Bridge becomes the Root of the Spanning Tree.
• Max Age (sec) is the timeout value for information transmitted by the Root. If the Root goes off-line,
the Bridge needs to timeout the stored configuration information and start again. This parameter can
be set and will be used if the Bridge becomes the Root of the Spanning Tree.
• Main Menu: Returns you to the Main Menu screen.
